Pulse Timer/Counter Input/Output, PWM output Raspberry Pi HAT board.

RPi-GP90 is a Raspberry Pi expansion board that has 16ch PWM output and 4ch programmable pulse input/output functions.(Count-up counter, Count-down counter, Up/Down counter, Phase counter, Period measurement, Pulse-width measurement, One-shot output, Square-wave output)

16ch PWM output and 4ch pulse input/output on the board.

This product has 16ch PWM output and 4ch pulse input/output on HAT size board.

8 functions are available with pulse input/output(4ch/16bit).

Each port can be used as repective functions.

Count-up counter	Add the two pulse count.
Count-down counter	Subtract the two pulse count.
Up/Down counter	Count Up/Down of pulse with defined direction.
Phase counter	Count 2-phase pulse.
Period measurement	Measure period of input pulse.
Pulse-width measurement	Measure pulse-width of input pulse.
One-shot output	Output one-shot pulse of specified time after detecting trigger signal.
Square-wave output	Output square-wave of setting width.

PWM output: 16ch/12bit, Adopt NXP PCA9685

Maximum of 16 servo motor and LED can be controlled. RPi-GP90 has power terminal for supplying 5V to motor and LED.

Isolates between PWM output/pulse I/O and GPIO40pin(Isolation Voltage 2.5kV)

Digital isolator that can isolates electrically between serial I/O and GPIO40pin is adopted as the isolating element.
It enables lower power consumption(low-heat-generating), smaller footprint, faster signal trasmission than standard photocoupler isolation.
